Choose the Sonar 70cm Surf Mast for prone foil surfing in waves. The 70cm is also an ideal height for learning to kitefoil, and for Freeride foiling in shallow waters. The precisely-crafted Mast section profile is constructed from aeronautical grade 6061-T6 Anodised Aluminium, with a well-balanced strength to weight ratio.

Engineered to last, with our unique GeoLock tapered geometry locking system. The Geolock provides a more effective load-bearing connection between the Mast and Fuselage, locking them together, so they feel like one piece. Screws engage the GeoLock while load transfer now takes place over the full cross-section of the mast profile, allowing for a more efficient load transfer and longer-lasting connection.
